Disconnect the charger if connected and then remove the battery from the laptop and then plug in the charger to the laptop and check if it turns on OK
Here's the hardware maintenance manual for the laptop. Go to p.35 to view the procedure to remove the battery pack.
If it turns on OK then the battery is faulty and needs to be replaced.
